is this poossibe on a mac?

cheers

Yeah, it is possible but a little cumbersom. In Quicktime 5 Pro the copy, cut and paste commands are greyed out when mpeg files are displayed. You can still join mpegs, however, by opening the first segment, moving the slider to the end of the clip, then opening a second segment and moving the right triangle below the slider all the way to the right. This "selects" the entire clip. Then just click on the movie window and drag it to the first clip window. You can now either "save" as a dependent movie (a short movie document that references the two segments, or use "Save As..." to save a self-contained movie. If more than two segments are involved just repeat the above step before you save the entire mpeg.
If you can find a copy of the Quicktime Player that comes with QT4 the edit commands are not greyed out, making the process a little less cumbersom. The QT Player4 is all you need, not the entire QT4 installation.

I tried doing this once. Cutting and pasting them is NOT the solution. You have to de-mux them into their audio/video components, and then use something like Final Cut Pro to join them together PROPERLY.

It has worked fine for me starting, I believe, back with QT3. As long as the mpeg was segmented properly it should join seemlessly without having to re-encoded. If the segments are not the same resoulution or they were not split exactly at the end of a keyframe (I frame in mpeg) and Delta frame sequence then you may have problems but that is not QT's fault. I think the moral of the story is to try to join them with QT Player and then if they fail to join, go on to the extra work of demuxing them and re-encoding, not before.

In general, copy and pasting does work with QT Pro. It's only when you got some glitch in one of the files that causes problems. Unfortunately, demuxing doesn't always work for files that QT has problems playing.

then you might try exporting from QT Pro as a DV stream. now import into iMovie each new DV stream (formerly a movie segment) and recombine from here. export to quicktime when done.

as a side note: copy-paste works for me with quicktime pro 5.

I have ported an app from sourceforge to mac os and macOSX its called mpgtx. It is a gerneral purpose mpeg editor. mpeg-1, mp3, mp2 and some mpeg-2 support. splits, joins, demux etc.on mpeg files.

the sourceforge page: http://mpgtx.sourceforge.net
the macintosh port: http://www.biermann.org/philipp/

works nice and fast especially on OSX. But beware, this is only a console app (since it fullfills my needs, I have not made a gui), so you have to read and type or otherwise are unable to use it.

thanks nobody! many of us mac-heads would love a gui. you'd even make versiontracker's page.

so if you've the time, try your hand at cocoa programming. I hear it's pretty easy.

That UNIX app has a GUI now and it works great in joining mpag1 segments!!! yay. See versiontracker or that homepage above. Version 1.4 beta 4 today.
